You get two lines with 
final<c> because that print is unconditional. You could write it that 
+way instead:

<c>
sub spl {
   my ($num1) = @_;    
   my $total = 0;

   $total = $total + $_ for (split '', $num1);
   if (length($total) == 1) {
      print "Final: $total\n";
      return $total;
   } else {
      return spl($total)
  }
}
